Hi @ayumi_vh,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your printer!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Restore Wi-Fi Setup Mode

Restoring your printer to Wi-Fi setup mode allows it to be discovered during the setup in the HP Smart app.

Turn on the Printer:

• Ensure the printer is turned on.

Restore Network Settings:

• For printers with a built-in display: Use the control panel menu to navigate to the Wireless or Network Settings menu, and select Restore Network Settings.
• For printers without a built-in display:
  • Press and hold the Wireless button and the Cancel button simultaneously for 5 seconds until the light starts blinking.

Set up the Printer using HP Smart App

Next, use the HP Smart app to connect the printer to your Wi-Fi network.

Download the HP Smart App:

• Download the HP Smart app from your app store:
  • Microsoft Store (Windows)
  • Mac App Store (macOS)
  • Google Play Store (Android)
  • App Store (iOS)

Open the HP Smart App:

• Open the app on your mobile device or computer.

Add Printer:

• Click Set Up a New Printer or Add Printer.
• Follow the on-screen instructions to detect and connect your printer.

Connect to Wi-Fi:

• During setup, select your Wi-Fi network and enter the Wi-Fi password when prompted.

Ensure Bluetooth is Enabled:

• Make sure Bluetooth is enabled on your device so the HP Smart app can detect the printer.

Enable Location Services (Mobile Devices):

• If prompted, enable the mobile device’s location service and allow the app to use your location.

I hope this helps.
